Application filed September 3 1907. Serial No. 391,10

T 0 all whom it may concern I Be it known that l, Emvann Sco'r'r, a citiof America, residing at Pittsburg, in the county of Allegheny and have invented certain j gines, of which the following is a specification, reference being had therein to the accom anying drawing.

Tfiisinvention relates to rotary engines, and its object is, to provide a simple and inexpensive engine adapted to be operated air.

The invention comprises a rotary piston of novel construction in combination with a casing provided with inlet and exhaust ports and'a revoluble shaft upon which the rotary piston is mounted.

The construction of the improvement will be fully described hereinafter in connection with the, accompanying drawing which forms a part of this specification, and its features of novelty will be set forth in the appended claims. I

In the drawing Figure l is a vertical section/and Fig. 2 is a transverse section of the same.

I The reference numeral 1 designates a circular casing provided at one side with an exhaust opening 2, and at its opposite side with a center hearing 3 for a shaft 4.

Within the casing l is a rotary piston 53 socured by a key 6 to the shaft- 4, said shaft being supported in bearings 7 and 8 at the upper ends of standards 9, and having a belt pulley 10 mounted thereon.

The rotary piston comprises a ring 5 having parallel flanges 11, a disk 12 provided with a hub 13 within which the shaft lissecured.

Pro'ecting radiallyfrom the ring 5 are serics of pins 14 each alternate row being out of vertical alinement with the next adjacent row ollpins. That is to say the rows of pins are arranged in staggered relation.

The numeral 15 designates a supply pipe for steam or compressed air, provided with a plurality of equi-distant inlets 16, four of said inlets being shown in the drawing to project motive ilUHl aga nst the pins-l4, to

revolve thepiston. I

The utility and operation of the engine Will The pins 14 afford 1 claim as new and extended hearing surfaces for the im not of the Silillll or air, and the shaft 4 is t lus rc'- volvcd conveying its rcvoluhle motion to any suitable machinery hy means of the belt pulley. i

The exhauststeam or air passes off through the exhaust opening 2 as isobvious from the drawing.

I would have it understood that the invention includes all such variations and modifical ions in the details o'f'consti'uction as may i all within the terms'ainl scope of theclaims.

Having fully described my invention What ters Patent, is:

l. A rotary cngipe comprising a circular casing provided with an exhaust openlng and desire to secureby Let- I a central hub, of a shaft support within said hub, with radial motive luid.

A; rotary engine comprising a circular casing-providcd with an exhaust opening and a central hub, of a shaft supported within said hub, a rotary piston on sakl sliaft provided n ith radial pins to receiwe the impact of the motive iluid, said pins being arranged. in ron s in staggered relation.

.5. A rotary engine comprising a circular casino; provided with an exhaust opening, and a central shaft bearing, of a shaft sup ortcd in said hearing, a rotary piston on sai shaft a rotary piston on sau shaft provided within the casing pins projecting from the.

periphery of the piston and arranged in rows, and a supply pipe for motive fluid rovidcd with inlets to project the motive ililid against said pins.

4. A rotary engine comprising a circular casing; provided with an'exhaust opening, and a central shaft i' earing,'of a shaft supported in said hearing,a rotary piston on said shaft within the casing pins projecting from the periphery of the piston and ar:

ranged in rows, and a supply'pipe for motive lhud provnled withinlets .to pro ect the motive l uid against said pins, said inlets-being located e ual distances apart to equalize the 'lorce of t 1e impact against the pins.

In testimony whereof I allix my signature in the presence of two witnesses.
